The document discusses data deduplication in Windows Server 2012, detailing installation, configuration, and optimization strategies. It provides insights on the types of files suitable for deduplication, evaluation commands, and expected outcomes, emphasizing efficiency and reliability. Additionally, it includes reference links related to deduplication performance metrics and management tools.

2. Deduplication?
Architecture
Installation - Config
Results / Conclusions
More Tips

5. In-line versus Post Process
Source versus Target
File-, Block- or Chunk-Based

7. Filter Driver
Service Based (ddpsvc)
Garbage Collection
Optimization
Scrubbing

10. Windows Server 2012
1 single CPU – 4GB Ram - SATA

11. GUI Based
Through Server Manager
PowerShell
Import-Module ServerManager
Add-WindowsFeature –name FS-Data-Deduplication

13. Can it be duplicated?
Empty volume?
Resources?
Unsupported Config?

14. Great:
{ File share | Virtualization Files | OS deploy files | Backup Files }
Maybe:
{ LOB | Web Servers | HPC }
Poor:
{ Hyper-V hosts | WSUS | SQL / Exchange Servers}

15. 5 Age default (last modified)
Schedule: every hour
No exclusions
Garbage collection /
data scrubbing on Saterday

22. Capacity optimization
Scale & Performance
Reliability & Data integrity
Bandwidth Efficiency w/ BranchCache
Management w/ Familiar Tools

25. Backups

26. DDPEval <VolumePath:>
Examples:
C:> DDPEVAL.EXE ServerTestshare
C:> DDPEVAL.EXE E:Test
C:> DDPEVAL.EXE F:
Will produce output similar to the following:
